Inherited Members

From UIElement

~this
~this()
Undocumented in source.
setId
void setId(const(char)[] identifier)

Set this element ID. All UIElement can have a string as unique identifier, similar to HTML. There is a maximum of 63 characters for this id though. This ID is supposed to be unique. If it isn't, a search by ID will return null. Chrome rules applies: can't contain any space characters.

getId
const(char)[] getId()

Get this element ID. All UIElement can have a string as unique identifier, similar to HTML. Returns the empty string "" if there is no ID. Note: this return an interior slice, and could be invalidated if the ID is reassigned.

id
const(char)[] id()
void id(const(char)[] identifier)

Properties to access this element ID.

hasId
bool hasId()
getElementById
UIElement getElementById(const(char)* id)

Search subtree for an UIElement with ID id. Undefined Behaviour if ID are not unique.

renderRaw
void renderRaw(ImageRef!RGBA rawMap, box2i[] areasToUpdate)

This method is called for each item in the drawlist that was visible and has a dirty Raw layer. This is called after compositing, starting from the buffer output by the Compositor.

renderPBR
void renderPBR(ImageRef!RGBA diffuseMap, ImageRef!L16 depthMap, ImageRef!RGBA materialMap, box2i[] areasToUpdate)
reflow
void reflow()

The goal of this method is to update positions of childrens. It is called whenever _position changes.

position
box2i position()
position
void position(box2i p)

Changes the position of the element. This calls reflow if that position has changed. IMPORTANT: As of today you are not allowed to assign a position outside the extent of the window. This is purely a Dplug limitation.

position
void position(box2f p)

Changes the position of the element. This calls reflow if that position has changed. Note: Widget coordinates are always integer coordinates. The input rectangle is rounded to nearest integer.

child
UIElement child(int n)
addChild
void addChild(UIElement element)

Adds an UIElement The addChild method is mandatory. Such a child MUST be created through dplug.core.nogc.mallocEmplace. Note: to display a newly added widget, use position setter.

removeChild
void removeChild(UIElement element)

Removes a child (but does not destroy it, you take back the ownership of it). Useful for creating dynamic UI's. MAYDO: there are restrictions for where this is allowed. Find them.

onMouseClick
Click onMouseClick(int x, int y, int button, bool isDoubleClick, MouseState mstate)

onMouseClick is called for every new click, whether or not you are in a dragging operation. This function is meant to be overriden.

Called when mouse drag this Element. This function is meant to be overriden.

onStopDrag
void onStopDrag()

Called once a dragging operation is finished. This function is meant to be overriden. Between onBeginDrag and onStopDrag, isDragged will return true.

onMouseEnter
void onMouseEnter()

Called when mouse enter this Element. This function is meant to be overriden. Between onMouseEnter and onMouseExit, isMouseOver will return true.

onMouseExit
void onMouseExit()

Called when mouse enter this Element. This function is meant to be overriden. Between onMouseEnter and onMouseExit, isMouseOver will return true.

void onFocusEnter()

Called when this Element is clicked and get the "focus" (ie. keyboard focus). This function is meant to be overriden.

onFocusExit
void onFocusExit()

Called when focus is lost because another Element was clicked. This widget then loose the "focus" (ie. keyboard focus). This function is meant to be overriden.

onKeyDown

Called when a key is pressed. This event bubbles down-up until being processed. Return true if treating the message.

onKeyUp
bool onKeyUp(Key key)

Called when a key is pressed. This event bubbles down-up until being processed. Return true if treating the message.

visibility
bool visibility()

Get visibility flag of the widget. A widget might still be invisible, if one of its parent is not visible.

visibility

setUserPointer
void setUserPointer(int pointerID, void* userPointer)

Set a user pointer. Allow dplug:gui extensions.

onDrawRaw
void onDrawRaw(ImageRef!RGBA rawMap, box2i[] dirtyRects)

Raw layer draw method. This gives you 1 surface cropped by _position for drawing. Note that you are not forced to draw to the surfaces at all.

onDrawPBR
void onDrawPBR(ImageRef!RGBA diffuseMap, ImageRef!L16 depthMap, ImageRef!RGBA materialMap, box2i[] dirtyRects)

PBR layer draw method. This gives you 3 surfaces cropped by _position for drawing. Note that you are not forced to draw all to the surfaces at all, in which case the below UIElement will be displayed.

onAnimate
void onAnimate(double dt, double time)

Called periodically for every UIElement. Override this to create animations. Using setDirty there allows to redraw an element continuously (like a meter or an animated object). Warning: Summing dt will not lead to a time that increase like time. time can go backwards if the window was reopen. time is guaranteed to increase as fast as system time but is not synced to audio time.

_parent
UIElement _parent;

Parent element. Following this chain gets to the root element.

_position
box2i _position;

Position is the graphical extent of the element, or something larger. An UIElement is not allowed though to draw further than its _position. For efficiency it's best to keep _position as small as feasible. This is an absolute "world" positioning data, that doesn't depend on the parent's position.

_children
Vec!UIElement _children;

The list of children UI elements.

_flags
immutable(uint) _flags;

Flags, for now immutable

_zOrder
int _zOrder;

Higher z-order = above other UIElement. By default, every UIElement have the same z-order. Because the sort is stable, tree traversal order is the default order (depth first). The children added last with addChild is considered above its siblings if you don't have legacyZOrder.

From IParameterListener

onParameterChanged
void onParameterChanged(Parameter sender)

Called when a parameter value was changed, from an UI control or through the host (automation). You'll probably want to call setDirtyWhole() or setDirty() in it to make the graphics respond to host changing a parameter. Note that this WILL be called from the audio thread.

onBeginParameterEdit
void onBeginParameterEdit(Parameter sender)

Called when a parameter value _starts_ being changed due to an UI element.

onEndParameterEdit
void onEndParameterEdit(Parameter sender)

Called when a parameter value _stops_ being changed.

onBeginParameterHover
void onBeginParameterHover(Parameter sender)
onEndParameterHover
void onEndParameterHover(Parameter sender)

Called when a widget that can changes this parameter is mouseover, and wants to signal that to the listeners.
